Special Problems of Management General Report

The papers to be presented in this Session show an interesting range of subject matter. Three discuss specific problems associated with existing mines, one deals with hydrogeological risk evaluation and one uses the impact of mine drainage on an aquifer to analyse a large-scale hydraulic parameter. Paper 1. Environment studies to determine the impacts of re-opening Banska Stiavnica-Hodrusa ore district in Czechoslovakia - Dusan Cababla - Marian Skaviniak. Future developments in established mining areas may have significant hydrogeological implications, especially where the existing mines are to be deepened. In turn this may have an impact in the area of the disposal of ever larger quantities of mine water, particularly, as is often the case, where the quality of this water is poor.
